intended for decoding DER-encoded P12/PFX files for use with the crypto/tls
package, and for encoding P12/PFX files for use by legacy applications which do
not support newer formats.  Since PKCS#12 uses weak encryption primitives, it
SHOULD NOT be used for new applications.")

Please double check because it tweaks 'update-cached-checkout' which is used
by "guix pull". :-)
